CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 245,611, dated August 16, 1881.

(Modem To all whom it may concern:

Be it known that 1, MARK A. DEEs, a citizen of the United States, resident at Scranton, in the county of Jackson and State of Mississippi, have invented certain new and useful Improvements in Oar-Brakes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification, and in which- Figure l is a sectional view of my carbrake, Fig. 2 is a top view, and Fig. 3 is a bottom view.

This invention relates to car-brakes, more particularly to the attachment of the handle to the staff in that class which is operated by hand.

The invention consists in the construction hereinafter specified.

In the drawings hereto annexed, A is the ordinary brake-staff, having a head, a, secured thereon in any suitable manner. Below this head there is sleeved upon statf A a cylinder, B, having the flange U beveli-d upward, and provided with ratchet c, forming a beveled gear-wheel, and a body,D, through which body passes a screw, d, for locking the cylinder to the staff.

Between head aand ratchet-flangeU, sleeved loosely upon staff A, is a block, E, free to turn on said staff, said block having lugs 12 c at one end, or a pin running therethrough. Pivoted upon these lugs e e by their passing through eyesffin its arms F F is a handle, G. This handle has on its under side a flange, H, concaved toward the staff A, and said concave having the ratcheted surface h, the concave corresponding in curve and bevel with the ratchet c, and the distance of ratchet h from the pivots c 6 being such that when the handle is lowered and arms F F rest on flange (J the two ratchets o and It will be in engagement. The bevel given to the wheel C and flange H causes a binding orjamming where they bite.

To use this device the handle is lowered until the ratchets catch, when the staff is turned to put on the brakes and is held by the pawl below, as is usual. To release the brakes the handle is lifted, the pawl is released, and the staff turns with block E, and there is no danger of injury being inflicted.

I am aware thatitis not new to have a ham dle to a brakestaff which can be thrown in and out of gear; but in this construction there is only a singlelug 0n the handle, which engages a groove on the staff-disk. If this log should miss the groove, as would be the casein a hurry, the device could not operate, and the turning of the handle would not affect the brakes. The present device can never fail.

What I claim is- A brake-stafl' having a beveled-gear whet-l aflixed thereto, in combination with a handle loosely connected to the brake-staif, and provided with a beveled concaved flange adapted to the gear-wheel 0n the staff, whereby the handle may be firmly connected to the staff or thrown off at will.

In testimony whereof I affix my signature in presence of two witnesses.

MARK ASHLEY DEES.
